Como pode, as leis básicas da física permitirem que todos os eventos sejam reversíveis. E somente uma delas dizer que nao? Nesse vídeo vou mostrar como conciliar isso. Ludwing Boltzmann, constatou que irreversibilidade do processos térmicos, como a condução de calor do calor, ocorre não de forma absoluta, certeira, mas de forma probabilística. Entropia probabilística e dispersão da energia. E essa foi a grande sacada!
